To put things into perspective, I live in the literal desert in Arizona.

We currently have an official heat warning—it is cooler here than in France.

@thomasfuchs France is a heck of a lot more humid, too.
@steve yeah it will maybe reach 110F here today but at 10% relative humidity

@thomasfuchs @steve

At the very least get yourself somewhere that is air-conditioned during the heat of the day.

It's one reason cinemas were such a draw during the depression. They had swamp coolers and then they had AC. A double feature could see you through an afternoon of heat.

Air conditioned shopping is also an option. How're the European museums? AC there as well I hope.

@MyWoolyMastadon @steve a lot of cinemas in Europe don’t have AC btw

@thomasfuchs @steve

Thanks for the heads up.

@thomasfuchs Used to open windows around 10pm to get some fresh air. But now if you want some fresh air you have to open them in the middle of the night 😂

@thomasfuchs

And lower humidity I'll bet.

@thomasfuchs right but the AC contributes to heating the external air so.. not the best solution

(of course the best solution is to prevent or reduce climate change as much as possible..)

@elduvelle 1. do you understand the ratio of inside air to outside air and 2. The heat is just moved from the inside to the outside (and heat from the outside will heat up inside again so it cools the outside)

it’s a zero-sum game, the overall heat does not increase

@thomasfuchs Hmm, I think that's wrong. The mechanical parts of the AC are going to create some additional heat. Plus it uses electricity which, unless it is from a renewable source, is going to create additional pollution somewhere else.

@elduvelle yes any electrical system has some heat losses, but it’s extremely marginal in a heat pump.

There’s basically a pump and a motor and a fan, with almost all energy that goes into it used for the pumping of heat energy with only extremely marginal losses.

It’s extremely efficient and clean running.

@thomasfuchs @elduvelle
In a greenhouse-like building, there is more heat created than in a bioclimatic building with louvers, white roof and walls, that radiate light back to the deep sky.
It is not a zero-sum problem but one very sensitive to greenhouse effect and albedo in architecture.
@elduvelle @thomasfuchs Especially with the denser population centers that a lot of Europe has. The heat island effect is already quite large here because of that, air conditioning will only exacerbate the issues, especially for those who cannot afford powered climate control. Instead we should demand climate adaptations of our neigbourhoods and cities, and planned climate adaptation renovations of houses that disadvantaged people live in.
@thomasfuchs honestly not buying AC in Europe (specifically for me here in the UK) is the cost, even the standalone units are a few hundred
@thomasfuchs I live in the Paris area. Our building is newly built, finished in 2023. It is not adapted to hot summers. I cannot afford AC right now. Last week, I had to cover my bed with gym mats and towels and go to sleep wet from the shower just to wake up three hours later drenched in sweat with a headache. The heat made my ears hurt. And I'm young and healthy.
@CASSCFenjoyer I’m so sorry. Please seek medical help as this could be serious.
@thomasfuchs I'm ok now, but thanks <3
(Our hospitals are at capacity anyways.)
